    It can be understood as representing the time, effort, and resources required to move from one event to another. A PERT activity cannot be performed until the predecessor event has occurred. PERT sub-activity: a PERT activity can be further decomposed into a set of sub-activities. For example, activity A1 can be decomposed into A1.1, A1.2 and A1.3.

  3. Design structure matrix - Wikipedia

    en.wikipedia.org/wiki/Design_structure_matrix

    A sample DSM with 7 elements and 11 dependency marks. The design structure matrix (DSM; also referred to as dependency structure matrix, dependency structure method, dependency source matrix, problem solving matrix (PSM), incidence matrix, N 2 matrix, interaction matrix, dependency map or design precedence matrix) is a simple, compact and visual representation of a system or project in the ...

  4. Subgoal labeling - Wikipedia

    en.wikipedia.org/wiki/Subgoal_labeling

    Generally problem solving adopts a very procedural approach. Problem solving in the areas of science, technology, engineering and mathematics has been highly procedural. The best approach so far is to teach these procedures through instructional text accompanied by specific worked examples.

  5. Critical path method - Wikipedia

    en.wikipedia.org/wiki/Critical_path_method

    Kelley attributed the term "critical path" to the developers of the PERT, which was developed at about the same time by Booz Allen Hamilton and the U.S. Navy. [5] The precursors of what came to be known as critical path were developed and put into practice by DuPont between 1940 and 1943 and contributed to the success of the Manhattan Project. [6]

  6. Directed acyclic graph - Wikipedia

    en.wikipedia.org/wiki/Directed_acyclic_graph

    An example of this type of directed acyclic graph are those encountered in the causal set approach to quantum gravity though in this case the graphs considered are transitively complete. In the version history example below, each version of the software is associated with a unique time, typically the time the version was saved, committed or ...

  7. And–or tree - Wikipedia

    en.wikipedia.org/wiki/And–or_tree

    A node N, labelled by a problem P, is a success node if there is a method of the form P if nothing (i.e., P is a "fact"). The node is a failure node if there is no method for solving P. If all of the children of a node N, conjoined by the same arc, are success nodes, then the node N is also a success node. Otherwise the node is a failure node.

  8. Expert system - Wikipedia

    en.wikipedia.org/wiki/Expert_system

    The expert system may choose the most inappropriate method for solving a particular problem. Problems of ethics in the use of any form of AI are very relevant at present. It is a closed world with specific knowledge, in which there is no deep perception of concepts and their interrelationships until an expert provides them.

  9. Eight disciplines problem solving - Wikipedia

    en.wikipedia.org/wiki/Eight_Disciplines_Problem...

    D0: Preparation and Emergency Response Actions: Plan for solving the problem and determine the prerequisites. Provide emergency response actions. D1: Use a Team: Establish a team of people with product/process knowledge. Teammates provide new perspectives and different ideas when it comes to problem solving.
